which verb ?


which sentence is correct?‎
Speed of the particles is measured.‎
Speed of the particles are measured.‎

speed is uncountable and we should use a singular verb for it. However we have "particles" that is ‎plural. Which verb should I use, singular or plural?‎

Yes, you should use the singular verb becaue "speed" is the subject, not "particles.". You also need "the" in front of speed. The speed of the particles is measured.

Patty is quite correct.



I do want to mention, however, why this is confusing you:

"particles" is plural and comes in front of your verb--this is why you want to use the plural verb "are" instead of the singular verb "is".


Patty is quite correct that "speed" is the subject, not particles.

As a student, the thing you need to understand is that "of the particles" is a prepositional phrase.

A prepositional phrase can never serve as your subject.

This is how you knew that the singular subject "speed" is the correct noun for agreement.



More examples that would confuse you:

One [of the girl scouts] is selling cookies.

               (singular "one", not plural "scouts"; hence, singular "is", not plural "are")

The dude [in the tight pants] is awesome.

               (singular "dude", not plural "pants"; hence, singular "is", not plural "are")


and so on.
